Operators of such equipment require to be well trained in all aspects of High-Voltage Safety.
For the first time in the Indian sub-continent, customized training is now available to the Maritime sector. Designed and developed by IMTC, the “High-Voltage Safety Course” offers invaluable benefits to Marine Engineers and Electrical Officers.
The Course includes practical hands-on exercises on an actual High Voltage Panel comprising of Vacuum Circuit Breaker, Earthing switch along with the associated interlocks, Potential and Current transformers, Bus Bar chamber and Low Voltage Safety Relay panel, thus familiarizing the participants with High-Voltage equipment and the various safety procedures for handling the same.
Course Objectives:
To enable the Participants to :
- Understand the working of the various specialized components & equipment used in High Voltage installations.
- Operate, maintain & troubleshoot High Voltage installations safely & efficiently.
- Learn through sharing of experience amongst participants.
Duration: 3 days
Suggested Target Group:
All Electrical Officers & Marine Engineers.
